GIMP :: Plugin Or Steps To Select Visible Portion Of A Layer In Image
Mar 26, 2013
I need to get the visible portion of a particular layer in the final image.Lets say i have 4 layers and some portion of each layer is visible in the flattened image i would like to get the portion from each of the layers. The input will be in xcvf format.I will ideally want to automate this and output to file in some format looking like this,
Layer1 ---> Co-ordinates of visible polygon from this particular layer in the image .
Layer2 ---> And so on.
How to proceed with the script. I think brute force is to take each non-transparent pixel and and find the same pixel in all above layers if it is not found it will be added to the region.Or something exists like selection from alpha combined with multiple layers ?
Or if there is a way to find out for an image with all layers visible which pixel came from which layer ?

Im just trying to select a portion of an image and the paste it to another layer.
1. Select a portion and copy.
2. Create new layer.
3. Select the new layer.
4. Paste.
The only thing i get is a kind of new layer that says: "Floating selection"

there's nothing in that dropdown menu for you to select your source image/layer in the Move Path plugin.I am using an XCF (Gimp) file, with many layers. I selected a particular layer, then I opened the Move Path plugin.

I'm brand new to GIMP, I just downloaded it to get into some simple pixel art.
I was going fine, but I've run into a problem. I'm trying to select a portion of my image using the rectangle tool, and then move it to a different location using the move tool. However, when clicking and dragging the move tool it shifts the entire image, not just the portion I have selected. I read in the FAQ that you need to press "Enter" to finalise the selection before you move it, but even doing that doesn't work.
This was working fine for me earlier, I'm not sure what I've done to break it. I've tried resetting my tool preferences back to defaults but that has not worked.

I already know about the Select-->By Color and then Edit-->Clear method of removing all of a certain color from an image. The thing I was wondering was what would be the best method in Gimp to select only certain portions of a certain color in an image and have them cleared out, not all of that color.
I attached an image to this post. In that image, I want to only remove the white background, not the white in the eyes of the white in the hands.

Is it possible to select a part of an Image on the background layer. And when you delete it, its removed from the rest of the layers as well.
Because I'm working with a DDS image and it has mipmaps (smaller and smaller copies of the background made as seperate layers.)

I'd like to be to select a layer groups and copy them over to another pre-existing image.
I've been struggling with this for an hour or so, and I haven't found a way to do this.
Is is possible to do this in GIMP?
The closet I've found is a kind of paste where you do this: drag the tab of the origin image over to the tab of the target image. The result is a new layer in the target image called "dropped buffer". However, the entire origin image is imported flattened.
I've been trying other drag and drop operations, but without success. Usually when I drop the selection to the target image, the icon under the mouse dissapears, and nothing actually happens.
I thought this might be a window manager problem. But I get the same results across kde, gnome and xfce.

Is there an option to move just a portion of a layer (with the Move, Scale, or Rotate tools, for example) without having to first copy the portion, then delete it, and then paste it as a whole new layer?
For instance, if you have a picture of a house and there's a tree off to the side, and you want to shrink the tree a bit so the house looks bigger. Currently, I would ( a ) copy the tree, ( b ) delete that selection, and ( c ) paste the tree as a new layer....and then finally (d) shrink that.
But could I simply select the tree and shrink it on the same layer?

I have a problem, gaps are visible between the steps when using 3D bevel on text in illustrator CS6, even after expanding appearance. It looks bad in illustrator and rasterized in photoshop, which is where I want it.

I have a PNG image with only one layer as a start point. It has a faded map on it.
I have a second PNG image with a hex grid on it. I do colour to Alpha to establish transparency on the hex grid for white filled hexes (others are not filled with white).
Now, I wish to overlay a portion of the first image with the faded map with the non-transparent part of the second image.
So I select by colour (for the hexes not filled with white) on the second image (the overlay) and I then paste to the first image (after creating a transparency layer and selecting it to receive the overlay).
I see the desired overlay section (minus any transparent stuff as expected), however it is centered over the map in the first image, not where I want it to be. It is a floating selection and must be anchored. So I select the anchor icon in the layer dialog and I think I anchor it into the transparency layer on the first image (that's what I'm trying to do anyway).
And then my problem:
I want to move the thing I just pasted in to the right place with respect to the underlying faded map. I attempt to use the move tool, but all I move is the background map (pretty much the opposite of what I want).
Nothing I do seems to let me reselect the pasted-in overlay so that I can move it.
Why I can't ever reposition the pasted in overlay? It should be in the transparency layer I created but even if I select all, I don't seem to be able to move anything other than the background image.

I have a large background image and I want to change (lower) the transparency of the header portion. I can select the portion with the rectangle, but after that I'm stuck. I tried changing opacity but it affected the entire image. I tried selecting Layer -> transparency -> add alpha channel, but that didn't do anything that I could see. How do I make the rectangle portion that I selected somewhat blurry?
Note: I did simply blur out the header portion of my image as one solution. But is it possible to add a layer over just the header part of the image and make that layer semi transparent?

I can't seem to copy a part of a layer into another layer. When I do that, the pasted layer becomes invisible. The pasted layer seems to be visible only when it's on its own layer.
Please see attached xcf.

I was working in Gimp last night with no problems at all. I modified an image of some fabric to create a texture then pasted that texture into another image and had happy results. I'm trying to do it again tonight with a different texture I created but when I try to paste it into the other image the pasted layer is not visible. The layer transparency is set to 100, and, of course, the 'show layer" eye is clicked.

Basically, I'm trying to make simple animations. For some reason, I can't figure out how to make any layer but the top visible. Is there any way to essentially make the layers have a visible/invisible function? I'm not talking about the eye button next to the layer name.

I have a nice image that has lost the red channel histogram data for about half of the image. It can still be viewed, and the preview is correct.
Can I copy the histogram data from the red channel of the non-corrupt portion of the image? I know it's the red channel because when I open the color data from the corrupted portion the red channel is literally non-existant.

I'm looking for a plugin that will merge one layer with all of the individual layers below it. So this would be the equivalent of duplicating one layer multiple times and then moving each duplicate between all the layers below and then merging the duplicate layers down to each original individual layer.
It could be seen as putting an ace on top of the deck, duplicating that ace 51 times, and then putting a duplicate ace in between each of the cards below and then merging each duplicate ace card down to each of the other individual 51 cards below in the deck.
I've found allot of nice multi-layer plugins (Like "LayerGroups") on the GIMP plugin registry that have worked doing things that I need, but now I'm looking for this one on the GIMP plugin registry and I'm not having any luck.

I wanted to install plugin "Layer-via-Copy-Cut", when I tried to extract to Gimps plugin folder I received an error that I needed "libgimpui-2.0-0.dll". I have only been using Gimp for several days and I installed the 2.8.2 version

I have had numerous problems trying to print from 2014 using the setting "Visible portion of current window". Â This feature was never that good, anyway, but now it seems to be WAY worse. Â I'm spending 5-10 minutes to just send something to the printer that should only take 5 seconds.
Â
See the attached images of what I see on screen, the print dialog boxes and then what I actually get. Â The "Center" option doesn't function properly and now I must manually adjust the margins to print what I see on the screen.

Apparently the issue has been happening since as far back as CS2. The flashing text cursor is only visible in the upper left hand portion of the screen. If the text your are attempting to edit is on the far right or bottom of the screen, the cursor vanishes. Some people have suggested zooming in and out, but this only appears to solve the problem because the art board may get nudged into the "good" portion of the screen. I did a screen shot and found that the cursor is only visible in about a 930p x 600p area of the window (not including toolbars). Incindentally, the is the same size that the window defaults to when initially opened. On a HD monitor, this amounts to a very small space.

I have some PDF files whose images are not visible as I go through the steps to open them. The steps are File > Open > select file in drop-down box > click on Open > see empty image in Import from PDF box > click on Select All > Import. The import process takes a few seconds and the editing box appears with a blank image. The size of the box matches the number of pixels shown in the import box, but no image is visible. What can I do to change the color or visibility of the pixels? Other PDF files import correctly using the same process.

first post from relatively new user of Gimp 2.6.7 on Vista.
I'd like to be able to quickly fit the image to the visible layers -- usually just one layer, in fact. I'm currently doing it by drawing a rough marquee and then correcting it at high magnification before using Fit Canvas to Selection, but there must be a better way! :roll:

I use gimp for image processing in my job as Forensic Questioned Document Examiner. One of the requirements when we elaborate an image is to be able to relate what modifications have been done to the image, in order to make the result reproducible.
So I was wondering: is there a feature or plugin that records all the modifications, filters, ... applied to an image (taking of course into account undos etc), and perhaps saves them into the resulting file (gimp format at least ) for later reference and inspection?

I've been a GIMP user for a couple of years and have just encountered a new and unexpected problem with version 2.8.4. I'm attempting to export a file to JPEG format, and am receiving the message:
"Saving 'FILENAME' failed: JPEG image plug-in could not save image."
I ensured I had adequate disk space, tried saving to different locations (including other drives on our network), tried resizing the image, and nothing will work. The message just recurs each time, no matter what I try.

In Gimp 2.8.4 on Ubuntu 13.04, I cannot select more than one layer. Shift+click does not work, so aligning layers is not possible either. The two packages I installed are Gimp itself and gimp-plugin-registry.

Okay I have been a avid user of Photoshop for years and I mean well over 10 years now. And I thought why not try something new, plus I saw something that GIMP could do that Photoshop couldn't so I went ahead a downloaded the program, but since I am so used to Photoshop I sort of expected GIMP to be almost the same as Photoshop and well it isn't. (Don't judge me now) so I have a few questions on certain things.
1: How do you select an object inside the layer, with PS you can just ctrl click in the window and poof it's there around your selected item, But GIMP doesn't do that so how do you do that in GIMP?
2: When using the circle tool, I get this green box thing around the whatever it's called and I don't see any marching ants. What am I doing wrong and how do I get that to go away if it's possible?
3: where is the crop tool? What does it look like?
4: How come some of the options for the brushes won't allow you the change them? like for instance, if I go to windows>brushes and double click on any of the brushes another window pops open and it says: Brush editor read only. What does that mean? You can't make any of the brushes in spatter brushes?

Recently upgraded to GIMP 2.8.6 and trying to select foreground item to use on different layer. Not working as I expected. Viewed demo on YouTube which indicated the last step or two would create a new layer and paste selected foreground on it.
When I attempt use the lasso tool, go over foreground with big brush and hit Enter, the foreground is selected but there is no new layer. I tried with no Alpha channel and tried making one before starting Foreground Selection Tool. Neither way seems to work. Am I wrong in understanding how the tool works, or am I leaving something out? Do I need to download a third-party Foreground Selection Tool? The video on YouTube is two years old but it seems to be talking about a "new" feature in GIMP.

Is there a way to select all the layers in the Layers Window? is: I've got a GIF animation that's comprised of 590 individual layers, and to work on specific layers, It'd be convenient to be able to hide all the layers other than the layer I'm working on - maybe with a dialog under Layers>>Stack>>Select all Layers>>Hide, or an "eye" checkbox at the top or bottom of the Layers window that would select all layers, thereby allowing me to "unhide" the selected layer by checking the "eye" ,(show), checkbox of the relevant layer.
Currently, the only way I know of to work on a specific layer within such a stack is to move the layer to the top of the stack so it becomes the visible layer, perform the work, then return the layer to its original location.
